This is exactly what I'm looking for ^^ I'm studying well because the lectures explain things so well. If I follow along and review, I think I'll be able to acquire enough knowledge about R.

Thank you for the great lecture.
Graphs using basic functions
ggplot2 Basics
Basic Graphs (Scatter/Line/Bar)
Learn R data visualization properly!
Come join us at [R for R] ✨
When analyzing data, how can we see the characteristics of the data we need to deal with at a glance? How can we find insights from the data more easily and better? Listed numbers or tables have their limitations. That is why data visualization is important.
The most popular R data visualization library,
Let's draw a graph with ggplot2 .
Scatter plots, line graphs, bar graphs, etc.
Learn how to present data effectively.
If you have some basic knowledge of R and can freely visualize data using basic R functions and the ggplot2 package, you will be very efficient .
OK to see the big picture

The time needed
It decreases.
I majored in business analytics for my master's degree at UNIST and started data analytics. I started working in the data analytics team from my first career, and I am currently constantly working on outsourcing related to data analytics as well as corporate/school lectures. 😎
Q. I don't know anything about R. Is that okay?
It's not okay at all. If you haven't taken [R for R] Basics, you should be able to install and load packages/input/output files/filter data frames to be able to take the course without difficulty.
Q. What is ggplot2? Why learn it?
There are many functions in R that can draw graphs, but they are too crude and difficult to handle, so I don't use them often. I will focus on learning the ggplot2 package, which helps me draw more attractive and pretty graphs more conveniently.
Q. Even if I learn this, won't I still be able to draw graphs with the data I have?
You will be able to draw graphs that can be inserted into papers on your own.
Q. How well will I do if I study and understand everything that comes out here?
It will be very helpful because it goes beyond just introducing various functions and provides hands-on practice using various data.
Please check!
